4 Claims.

This invention relates to new and useful improvements in air conditioning apparatus. of the character used for air conditioning the rooms of buildings, boats, etc.

The principal object of the present invention is to provide air conditioning unit which will occupy a very limited space, and which in operation will be positive acting and not susceptible to the ready development of defects.

Another important object of the invention is to provide an air conditioning apparatus which will be of simple construction and of low cost to install.

These and various other important objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings:

Figure 1 represents a vertical sectional view through the housing of the apparatus.

Figure 2 is a top plan view of the apparatus with the top removed.

Figure 3 is a vertical sectional the apparatus.

Figure 4 is a section on the line 4-4 of Figure 3.

Figure 5 is a fragmentary sectional view on line 5-5 of Figure 3.

Figure 6 is a fragmentary sectional view on line 6-6 of Figure 3.

Figure 'I is a perspective view of one of the battles.

Referring to the drawings wherein like numerals designate like parts, it can be seen that the housing of the apparatus consists of the bottom wall 5, the side walls 6-6 and the end walls I--8. These walls are made up of outer and inner plates between which a suitable heat insulating filler is located. Numeral 9 denotes a top for removable disposition upon the housing and this is constructed in the same manner as the bottom and upright walls.

In the housing is located the shell III which has an air inlet opening H in one side thereof. In this shell is the semi-circular baffle A. Transversely disposed through the shell I0 is me shaft I2 on which is the suction-blower fan l3. One end of this shaft l2 outside of the shell I0 is provided with the pulley ll. An angle shaped bracket i5 is secured to the end wall 8 and from this inclinedly supports the arm l6 which is atview through tached as at I! to the top of the shell II! to asf sist in supporting the shell. Numeral l8 represents a conduit which extends from the shell in and is curved upwardly as at I 9. Numeral 20 represents the outlet through the top 9, the

upper end portion of the conduit being offset laterally as at 2| to meet the said outlet 20, and innthis offset 21 are the vertically extending baffies22 intersected by the baiiies 23 which are provided with inclined upper portions 24 deflecting 5 the treated air as it rises from the conduit to the outlet '20. Below the baflles 23 and partitions 22 is the bailie bank generally referred to by numeral 25, while in the curved portion ill of the conduit are the concentrically disposed curved de- 10 fiectors 26. Between the fan shell l0 and the deflectors 26 are two batteries 2l28, of defiec- I tors such as on the bank 25. These deflectors are constructed as shown in Figures 5 and 7 and are adapted to remove a considerable amount of moisture from the air as a result of condensation. The same are parallel disposed strips" 29 each of which is provided with a V-shaped channel 30 and these channels define ribs 3|. The strips are assembled with the rib sides 3| opposing the channels 30 of opposed s'trips.

On the vertical portion of the conduit 18 is mounted the pump 32 which has the shaft 33 on which is a pulley 34. Extending downwardly from the pump 32 is the eduction pipe a having a strainer inlet 35 at its lower end. The lower portion of the housing is to contain cracked ice or brine (or refrigerating apparatus if desired) and the pump32 serves to draw the cold liquid upwardly and transfer the same to the depending pipes 36 which extend downwardly at the sides of the conduit It to merge with the spray pipes 31 so that the cold liquid from the bottom of the housing can be sprayed onto the sides of the conduit I8. 35

A draincock 38 is provided in the pipe 39 from the pump 32 to the pipes 36.

A motor 40 is mounted on the inclined arm l6 and has the pulley ll on its armature shaft. A belt 42 is trained over the pulleys I4, 34 and 4|, as shown in Figure 1 so that the fan l3 andpump 32 are driven simultaneously.

Refrigerating coils 43-.--l3 are arranged in the lower portion of the housing, as suggested in Figure 1.

It can also be seen in Figure 6 that the upper portions of the partitions 22 are obliquely disposed as shown in Figure 6 and denoted by reference character 22a.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape,

. size,v and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

from the shell, said conduit merging with an upwardly disposed stack terminating at the conditioned air outlet, liquid temperature changing means in the lower portion of the housing, a pump mounted in the upper portion of the housing and having an eduction pipe extending from the lower portion of the housing thereto, and

spray pipes extending from the pump downward- -ly and along the horizontal conduit longitudinally and constructed to spray liquid onto the horizontalportion of the conduit to cool air forced therethrough by the blower.

2. An air conditioning apparatus comprising a housing having a conditioned air outlet, a blower and a shell therefor mounted in the housing, a conduit extending horizontally in the housing from the shell, said conduit merging with an upwardly disposed stack terminating at the conditioned air outlet, liquid temperature changing means in the lower portion of the housing, a pump mounted in the upper portion of the housing and having an eduction pipe extending from the lower portion of the housing thereto, and spray pipes extending from the pump downwardly and along the horizontal conduit longitudinally and constructed to spray liquid onto the horizontal portion of the conduit to cool air forced therethrough by the blower, the point at which the conduit merges with the stack being of curved construction and concentrically arranged deflectors in said curved portion.

3. An air conditioning apparatus comprising a housing having a conditioned air outlet, a blower and a shell therefor mounted in the housing, a conduit extending horizontally in the housing from the shell, said conduit merging with an upwardly disposed stack terminating at the conditioned air outlet, liquid temperature changing -means in the lower portion of the housing, a

pump mounted in the upper portion of the housing and having an eduction pipe extending from the lower portion of the housing thereto, and spray pipes extending from the pump downwardly and along the horizontal conduit longitudinally and constructed to spray liquid onto the horizontal portion of the conduit to cool air forced therethrough by the blower, the point at which the conduit merges with the stack being of curved construction and concentrically arranged deflectors in said curved portion, and transversely disposed retarding baiiles in the stack immediately above the said concentric bafiies.

4.. An air conditioning apparatus comprising a housing having a conditioned air outlet, a blower and a shell therefor mounted in the housing, a conduit extending horizontally in the housing from the shell, said conduit merging with an upwardly disposed stack terminating at the conditioned air outlet, liquid temperature changing means in the lower portion of the housing, a pump mounted in the upper portion of the housing and having an eduction pipe extending from the lower portion of the housing thereto, and spray pipes extending from the pumpdownwardly and along the horizontal conduit longitudinally and constructed to spray liquid onto the horizontal portion of the conduit to cool air forced therethrough by the blower, and transversely extending bailies in the horizontal conduit at the point where the outside of the conduit is contacted by liquid from the spray pipes.
